Hi, Jim,
To run on multiple nodes, you need to give a hostfile to mpirun.
However, it is a current limitation of the PGAS runtime that the first
node in the hostfile has to be the origin machine (i.e., the machine you
invoke mpirun on). You will also need to
export OMPI_MCA_orte_base_nodename=`hostname`
before launching mpirun.
We are working on fixing these issues.

You need to invoke manager through an absolute or relative path.
It does not work when invoked via the PATH.

Hope this helps,
